Abstract
The utility model discloses a steering hydraulic cylinder for an explosion-proof forklift. The steering hydraulic cylinder comprises a piston rod, cylinder covers, shaft sleeves, set screws, steel backing sleeves and a cylinder barrel. The piston rod is arranged in the cylinder barrel. The two ends of the piston rod are supported on the inner wall of the cylinder barrel through the shaft sleeves. The steel backing sleeves are pressed into inner holes of the shaft sleeves. The shaft sleeves are fixed at the two ends of the cylinder barrel through the cylinder covers. The cylinder covers are fixed on the outer wall of the cylinder barrel through the set screws. According to the steering hydraulic cylinder, the problems that the piston rod is easily scratched by an integral cast iron shaft sleeve and that the shaft sleeve falls due to vibration are solved; and the steering hydraulic cylinder has a simple structure and a simple design, and is easy to mount and convenient to use and maintain.
Description
Technical field
The utility model relates to the oil hydraulic cylinder technical field, specifically belongs to a kind of explosion proof forklift hydraulic steering cylinder.
Background technique
Existing hydraulic steering cylinder, screw thread and cap are adopted in the oil hydraulic cylinder two ends, and under vibrations, the also cap at the oil hydraulic cylinder two ends of this structure gets loose easily.Axle sleeve is whole cast iron, with the piston rod direct friction, abrades piston rod easily.Piston rod adopts quenching with Subsequent tempering, and surface hardness is low, causes scuffing easily, collides with, weares and teares, and working life is low.Have only 1 O-ring seals on the axle sleeve, break when this O shape is enclosed, oil hydraulic cylinder can cause large-scale external leakage.
The model utility content
The purpose of the utility model provides a kind of explosion proof forklift hydraulic steering cylinder, has solved whole cast iron axle sleeve and has abraded the problem that piston rod and axle sleeve come off because of vibrations easily, and is simple in structure, easy mounting, and simplicity of design, easy to use, be convenient to safeguard.
The technological scheme that the utility model adopts is following:
A kind of explosion proof forklift hydraulic steering cylinder; Comprise piston rod, cylinder cap, axle sleeve, Cock screw, steel backing cover and cylinder barrel; Described piston rod places within the cylinder barrel, and two ends are supported in inner wall of cylinder through axle sleeve, is pressed into the steel backing cover in the endoporus of axle sleeve; Axle sleeve is fixed on the two ends of cylinder barrel through cylinder cap, and cylinder cap is fixed in the cylinder barrel outer wall through Cock screw.
In the described axle sleeve and put to arrange and be provided with 2 O RunddichtringOs, improve the sealability of oil hydraulic cylinder, effectively solved the oil hydraulic cylinder external leakage.
Described steel backing cover inner hole wall greatly reduces itself and piston rod friction factor with teflon, and piston rod slides freely.
Described piston rod surface has adopted superaudio to quench and has carried out chromium plating and handle, and surface hardness is very high, has reduced piston rod and in transportation and using process, has caused external leakage, the working life of well having improved piston rod because of colliding with, scratching.
Compared with present technology, the beneficial effect of the utility model is following:
The utility model fork-truck steering hydraulic cylinder structure is simple, is easy to installation and maintenance.Efficiently solve the external leakage of fork-truck steering oil hydraulic cylinder, improve the durability and the resistance to pressure of oil hydraulic cylinder, prolong the working life of oil hydraulic cylinder.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to accompanying drawing; A kind of explosion proof forklift hydraulic steering cylinder; Comprise piston rod 1, cylinder cap 2, axle sleeve 3, Cock screw 4, steel backing cover 5 and cylinder barrel 6, piston rod 1 surface has been adopted superaudio to quench and has been carried out chromium plating and handle, and surface hardness is very high; Reduced piston rod 1 and in transportation and using process, caused external leakage, well improved the working life of piston rod 1 because of colliding with, scratching.Piston rod 1 places within the cylinder barrel 2, and two ends are supported in cylinder barrel 6 inwalls through axle sleeve 3, is pressed into steel backing cover 5 in the endoporus of axle sleeve 3, and steel backing overlaps 5 inner hole walls with teflon, and itself and piston rod 1 friction factor are greatly reduced, and piston rod 1 slides freely.Axle sleeve 3 is fixed on the two ends of cylinder barrel 6 through cylinder cap 2, and cylinder cap 2 is fixed in cylinder barrel 6 outer walls through Cock screw 4.In the axle sleeve 3 and put to arrange and be provided with 2 O RunddichtringOs 7, improve the sealability of oil hydraulic cylinder, effectively solved the oil hydraulic cylinder external leakage.
